FASTENING FOR TOOL-HANDLES.

SPECIFICATION forming part of Letters Patent No. 567,676, datedSeptember15, 1896. Application filed \Tune 27, 1896. Serial No. 597,189. (Nomodel.)

To all whom it may concern:

Be it known that we, ALFRED BOHY and LOUIS FRITZ, citizens of the UnitedStates,residing at Whatcheer,in the county of Keokuk and State of Iowa,have invented certain new and useful Improvements in Fastenings forTool-Handles; and we do declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements inhandle-fastenings, and especially to a fastening whereby a head of atool may be detachably held to a handle by means of an adjusting-nutwhich causes the lugs on the end of the handle to be securely seated inrecesses in the walls of the head of the tool.

A further part of the invention relates to the provision of an aperturedhead having laterally-extending recesses therein, the upper end of thehandle being provided with integral lugs and a screw-threaded nut bywhich the lugs may be drawn into the said recesses, to securely hold thehead in place on the handle.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination, andadaptation of the parts, as will be hereinafter more fully described,and then specifically defined in the appended claims.

We clearly illustrate our invention in the accompanying'drawings, which,with the letters of reference marked thereon, form a part of thisspecification, and in which drawings similar letters of referenceindicate like parts throughout both the views, in which- Figure l is aperspective View of the handle and head removed therefrom. Fig. 2 is acentral vertical longitudinal View through the head and handle.

Reference now being had to the details of the drawings by letter, Adesignates the head of the tool, which in the present case is a pick,and is provided with the central aperture B for the reception of the endof the casting O, which fits over the end of the handle D. The

aperture B is cylindrical in outline as far as the shoulder E, and fromsaid shoulder the aperture is square or oblong and is recessedlaterally, as seen at e. The casting O has its upper end contracted andterminates in laterally-extending integral lugs O with a curved upperend. The portion of the casting which conforms in size and shape withthe cylindrical-shaped aperture in the head is screw-threaded a portionof its length, as seen at F, and G is anut working on saidscrew-threaded portion of the casting.

When the head is to be adjusted to the handle, the solid end of thecasting on the handle is inserted through the aperture in the head untilthe under side of the head comes in contact with the upper face of thenut, and when in this position the lugs at the upper end of the castingproject above the upper face of the head a sufficient distance to allowthe handle to be rotated. The head of the casting after being turnedone-half of a revolution is in such a position that the said lugs willregister with the lateral recesses in the head, and when seated thereinthe nut is screwed up against the under side of the head and the handleis securely locked in place. By a reverse operation the handle may beremoved.

Having thus described our invention, what we claim to be new, and desireto secure by Letters Patent, is-

In a tool-handle-fastening device, the combination with the handle, acastingcarried on one end, a portion of said casting screwthreaded, anut carried thereon, the end of the casting contracted, and havinglaterallyextending integral lugs thereon, of the head of the tool havinga central aperture cylindrical a portion of its length its upper portionrectangular in shape and the lateral recesses e in which the said lugsare designed to be seated, substantially as shown and described.

In testimony whereof we aflix our signatures in presence of twowitnesses.

ALFRED BOHY.

his LOUIS FRITZ.
